Standard LaTeX expressions can be cut and pasted directly into WordPress posts, pages, and comments; display environments require no enclosures, other expressions require only a surrounding $..$ or \[..\]. No need for enclosing tags [latex] ... [/latex].

Correct vertical positioning of inline formulas relative to baseline of surrounding text. Say “NO” to jumpy equations produced by other plugins!

SVG vector graphics support, so that formulas are crisp regardless of scaling in browser.

Just place LaTeX math expressions into your text and enable QuickLaTeX on the page by [latexpage] command.
WP QuickLaTeX will convert them to high-quality images and embed into post. Inline formulas will be properly aligned with the text.
Displayed equations will be auto-numbered by LaTeX rules.
To see plugin in action please visit math-pages on my blog, e.g. Central Differences,Cubature formulas for the unit disk, Smooth noise robust differentiators, etc.

Some sloppy code in there that I had to manually fix. Also, this plugin was last updated 2 years ago. For example, 'eqlabel' > null has broken a multitude of websites.
Obvious fix is to deal with the typo, which shows me they didn't even test before deployment. For those that need to fix it before moving to something better, here's the "obvious" fix for that "eqlabel" snafoo:
'eqlabel' => null
You can fix that in the plugin file at /your-websites-root-directory/wp-content/plugins/wp-quicklatex/wp-quicklatex.php

For my regular posts I used JetPack renderer ($latex ... $)
However, it is not available in BBPress forum. Though QuickLaTeX is per default neither available, this hack solves the problem

@antonv, thank you, keep up a good work and I suggest to integrate the support for BBPress by default.
